Paul buys 5 bags of chips and 9 bags of pretzels for $16.95. Ian buys 1 bag of chips and 1 bag of pretzels for $2.55. Find the cost of one bag of chips and one bag of pretzels.

The cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

Step-by-step explanation:

Let x= Cost of one bag of chips

y= Cost of one bag of pretzels.

As per given, we have

5x+9y=16.95        ...(i)

x+y=2.55            ...(ii)

Multiply 5 to (ii), we get

5x+5y=12.75     ...(iii)

Eliminate (iii) from (i), we get

Put value of y in (ii), we get

Hence, the cost of one bag of chips is $1.5 and cost of one bag of pretzels is $1.05.

If a large cloud encounters a colder air mass, it tends to rise up in the sky. On the other hand, the cold air mass sinks toward the surface. This happens because temperature is a property that affects the density of substances. Colder substances are denser than warm substances.
